and pigs and bars were even exported to France. After 

 the conquest the works were leased to private parties, and 

 since then have passed through many hands." 



" Many samples of the articles —notably stoves — manufac- 

 tured from the pig iron made in those early days, still re- 

 main to attest the high quality of the iron." 



The furnace at Radnor, though similar in construction to 

 that at St. Maurice, from which it is only four miles dis- 

 tant, was erected at a much later date, and in some respects 

 it may be considered the successor of the old St. Maurice 

 furnace. At present the latter is idle, but that at Radnor 

 is in blast. Recently, the ore used and the pig iron produced 

 in this furnace have been analysed. The ore is a mixture of 

 equal parts of the bog ore of the neighborhood and of the 

 curious "lake ore" from Lac la Tortue. An average 

 sample of each was submitted to analysis, and the results 

 are given below : — No. 1 is the bog ore, No. 2 the lake ore, 

 No. 3 is a lake ore from the same locality, analysed by Mr. 

 W. A. Carlyle, B. A. Sc, some three years ago. 1
